The latest version of EPIC (electric potential integrated circuit) sensors from Plessey Semiconductors, the PS25401, is suitable for movement detection in security, switching and gaming applications. By detecting changes in the electric field, the sensor provides an output to a relay to act as a simple non-touch electric switch. It can be used in both proximity mode or to detect specific kinds of movement as a limited gesture recognition device. As the movement sensor does not need line of sight and can even detect movement through walls, it can also be used to replace, or as an adjunct to, a passive infra-red sensor in security motion detectors, says the company. The sensor can be used in medical applications as an ECG sensor and as a simple switch in electrical systems including toys, smart lighting, gaming and security.
